Expert Solution
Step 1

 

Solution-:

 Here, we want to test 

H0: Rows and columns are independent of each other.

Vs

H1:Rows and columns are not independent of each other. (or They are associated with each other)

We want to find 

(a) The expected frequency for each cell.

(b) χStat2=?

(c) Is it significant at a = 0.01?
